Might be related to #84, except getSupportedLanguages() returns a valid array (see log).

We’re seeing the same issue on 16.3.1

I just tested it with my iPhone 13 with iOS 16.3.1 and could not reproduce the issue.
So unfortunately I can't debug any further. PRs are welcome.

hi everyone, i have the same problem too. On my case, the plugin was fine 2 weeks ago, but now is muted en IOS...
On the xcode console, is printing this errors:

⚡️ To Native -> TextToSpeech speak 72170864
2023-04-19 10:51:08.190741-0300 App[7643:6907181] [catalog] Unable to list voice folder

And this is my code:
TextToSpeech.speak({
text: this.content.title,
lang: 'es-AR',
voice: 2
})

I did try whit es-Es or en-US on lang... or voice: 1, 2, 10, etc...
The method "getSupportedVoices returns some voice, this is aparently working fine.

Thanks a lot! I hope your help!
